General Information

Ampco’s ROLEC DH utilizes a SBI shear pump to recirculate a fermenter and simultaneously

induce hop pellets into the stream of beer. The hop pellets remain dry until they meet the

stream of beer. A pressurized chamber that is purged of air and constantly filled with CO2 is

used to induce the pellets for fermenting, finished, or crashed beer.

Ampco Pumps Company Powder Mixer Manual M-031 Rev A 12.20 Page 4

Unit Overview

Ampco’s PM Powder Mixer is a proven design that includes a liquid ring pump and a shear blender for fast blending. The easy use design provides high-performance blending of wet and dry ingredients into one fluid stream.

Because the SP Liquid Ring Pump provides consistent suction from the hopper, there is no plugging of product in the inlet flow area. The powder addition rate is steady, even when viscosity increases.

The rotor-stator design of the SBH Shear Pump provides smooth blending of product, eliminating lumps and clumps and offers repeatable batch-to-batch blending.



How It Works 1.The fluid from the batch tank is drawn in from the SP liquid ring pump.

2. Powder and fluid meet in the induction tube when the hopper’s valve is opened.

3.Mixing begins in the SP pump – the mixture flows through a short transfer tube into the ShearPump.

4. The Shear Pump (SBH) runs at high speed to thoroughly mixing the fluid and powder.

5. The final mixture is pumped to a batch or process tank.

A - Ampco SP Liquid Ring Pump B - Ampco SBH Shear Pump

C - Powder Hopper D - Powder Control Valve E - Fluid Control Valve

F - Dual-Motor Starter



Unit ConfigurationTo prevent suction head loss, be sure the PM Powder Mixer is no more than ten (10) feet from the mixing tank. Study the drawing below. Check the system pressures listed. These pressures must be established so the PM Powder Mixer operates at its optimum efficiency.

* In front of the liquid control valve (V1), pressure should be 1 to 5 psig.

*Placement of the PM Powder Mixer more than ten (10) feet from the batch tank may requireusing a feed pump to the mixer. If a feed pump is required, it is recommended that you use abalance tank to dissipate the pressure at the inlet of the mixer.

*Discharge pressure should be no more than 15 psig for the SBH Shear Pump. If thedischarge pressure is higher than the 15 psig, it is recommended you add a booster pump tomove the product from the mixer.

Due to the high vacuum created at the suction of the PM Powder Mixer, it is recommended suction rated hoses are used on the inlet side of the mixer. Ampco also recommends using hoses of like size to the inlet and outlet ports of mixer.

Pump



Electrical Control panels on the PM Powder Mixer are standard NEMA 3R & 12 and require 40 or 60 amps at 460 volts. Control panels can be customized to suit customer requirements. See chart below for voltage, volt, and amperage for each model.

For electrical hook up to the control box, run the electrical cord through the access hole in the bottom of the box. Connect the cord to the terminals near the main switch in the control panel.

A check should be made that the pumps have the correct impeller rotation. To do so, first shut the throttling valve (V1). Fill the unit with water until the water is visible in the sight glass. Mechanical seals should be completely wetted. Running the pumps dry can result in seal damage.

Switch on both the SP Liquid Ring pump and the SBH Shear Pump for a brief time to check the rotation. The direction of the rotation should be clockwise when viewing from the fan end of the motor. If the rotation is incorrect, switch the wires fed into the control panel.

Operating

1. Shut the valve for the powder inlet (2).

2. Allow liquid to flow from the tank to the mixer by fully opening the liquid control valve (1).

3. Turn on the SP Liquid Ring (3) pump and circulate the base liquid until there is full flow.

4. Turn on the SBH Shear Pump (4).

5. To allow sufficient vacuum to build, the liquid control valve (1) should be closed to

approximately 50%. To decrease the vacuum and slow down the flow of the powder into the

mix, slowly open the liquid control valve.

6. Open the valve for the powder inlet (2). Check the suction by placing the back of your hand

over the opening at the bottom of the hopper. If there is not sufficient suction or liquid is

coming up through the hopper, slowly close the liquid control valve (1) until you achieve

sufficient suction.

7. Close the valve for the powder inlet (2).

8. Fill the hopper with powder.

9. Slowly open the valve for the powder inlet (2).

10. To prevent air from being drawn into the product, close the valve for the powder inlet as

soon as the hopper is empty.

11. If the product is shear-sensitive, the SBH Shear Pump should be shut off immediately.

12. Product may be circulated back through the mix for more blending.

Note: Products like gums or pectins that swell require that you add the powder slowly so the pumps do not plug. To slow the addition of these powders, open the liquid control valve (1) to reduce vacuum. The valve for the powder inlet valve (2) should be only partially opened .

Maintenance Ampco Pumps Company


Maintenance

The PM Powder Mixer should be cleaned after each use. If not properly cleaned, product residue may dry on the mechanical seal faces of the pumps and cause damage when the mixer is next started.

The mixer may be included in an existing CIP system. The hopper, induction tube, and control valves should be cleaned by hand after being removed from the unit. Simply disconnect the clamps and remove the pieces.

Installation Ampco Pumps Company


SB & SBH Pump Installation

Receiving Pumps

Visually inspect shipping crate(s)/pallet(s) for damage. Ampco pumps will be shipped in boxes labeled Ampco Pumps or in crates. If there is any damage it is imperative to notify the driver at the time of delivery. Failure to do so will make it difficult, if not impossible, to file a damage claim and Ampco Pumps will not be held accountable. Please contact Ampco Pumps shipping department with damage details ASAP.

Once unpacked, carefully inspect the pump for any damage that may have occurred during shipping. Using a 15/16” socket, an extension drive, and ratchet turn the impeller nut to make sure the impeller turns freely. There should be a little noise from the seal which is normal. If there is metal to metal contact when the impeller is turned shipping damage is likely. Leave the protective covers on the inlet and discharge connections until the pump is installed and is ready to be connected to piping.

Pump Location Install pump in an optimal location. Be sure that there is room around the pump so it can be accessed readily for maintenance. Ensure that the motor has adequate ventilation. Make sure the motor type is suitable for the environment in which it is installed.

Electrical Installation Have a qualified electrician connect the motor using sound electrical practices. Do not test run the motor with the pump dry. Mechanical seals can be damaged running dry even momentarily. The pump must be flooded and the flush must be connected with flushing water flowing before starting the pump. The pump and motor has been selected for a specific environment and system application. Changing the environment or system conditions (i.e. change of fluid, change in head losses, change in NPSHr) can overload the motor. When changing system conditions or when in doubt, contact Ampco Pumps Company for technical assistance and someone will be ready to assist.

Installation Ampco Pumps Company


Pump Operation Make sure the pump is clean and free of any foreign matter.

Once the motor, flush, and piping all have been properly connected, the flush is turned on and is visibly flowing (if the pump has a flush option) and the pump has been flooded, the pump can be momentarily turned on to check the motor rotation. The correct rotation is counter-clockwise while looking at the pump from the suction end and clockwise if looking at the pump from the motor end.

When the rotation of the motor has been verified to be correct the pump is ready to run

continuously for service.

Seal Removal & Changing Shims

ATTENTION: Before attempting any service on the pump or motor, disconnect or lockout electrical power to the pump motor. If the pump and motor are to be removed as a unit, note the wiring and configuration. Use colored or numbered tape to mark the wire connections of the pump motor and power source for reconnection.

Tools required to disassemble and remove seal:

∗ 7/16” wrench ∗ Torque wrench

∗ 15/16” socket wrench ∗ 3/8” round bar

∗ 90o o-ring pick ∗ Dead blow hammer

1. Disconnect electrical power to the pumpmotor and follow any lockout/tag-out proce-dures in place at your facility.

2. Disconnect pump from the suction piping.Drain all fluids from the pump.

3. Loosen cover nuts with a 1-1/4”wrench. Remove cover wing nuts, flatwashers (if provided), lock washers (ifprovided), cover, cover gasket, and shaftguard. See Figure .

4. Insert a 3/8” bar in the hole in thestub shaft. See Figure 2. Loosen theimpeller nut. Turn the impeller nut witha 15/16” wrench counter-clockwise.

8. Push the stationary seal out from the backof the pump using an o-ring pick, your fin-gers, or both. Pushing on opposite sides ofthe shaft with constant light pressure, makesure to push outside of the rear seal face.See Figure 6.

9. Remove stationary seal once pushed outof its’ bore. See Figure 7. Check the condi-tion of the casing, rotating seal, and station-ary seal. Clean and remove any foreign mat-ter before reinstalling the seal.

Figure 7

Figure 6



Pump Assembly and Seal Installation

When replacing the seal assembly lubricate all o-rings with food grade lubricant. Once the

pump is fully assembled turn the stub shaft a few revolutions by hand making sure it turns

relatively freely and nothing is rubbing inside the pump. Running the pump with foreign

objects in the pump or having the impeller making contact with either the cover or the casing

will result in serious damage if not completely destroying the pump.

1. Use a food grade lubricant to lubri-cate all o-rings. It is important thatthe stationary and rotating seal o-rings are lubricated to ease assem-bly. Slide the stationary seal overthe shaft and into the casing, Figure8.

2. Line up a flat on the stationaryseal to the a flat of the window of thecasing and gently press the station-ary seal into the casing bore. SeeFigure 9.

3. The stationary seal should beproperly seated, as shown in Figure10, before continuing the assemblyof the pump.

Figure 8

Figure 9

Figure 10



3. Assemble the rotating half of theseal. Insert the single seal springinto the seal driver. The single sealspring is smaller than the rotatingdouble spring. Next insert the back-up ring. Insert the single rotatingseal o- ring then insert the single ro-tating seal. Be sure to line up theslots in the rotating seal with the pinsin the seal driver.

4. Install inner seal driver o-ring, thenslide the rotating seal assembly ontothe stub shaft, as seen in Figure 12,against the stationary seal. Be surethe outer seal driver o-ring is in the o-ring groove in the seal driver.

5. Insert key into the keyway in thestub shaft, Figure 13.

7. Before installing the impeller lubri-cate the impeller o-ring so it will stayin the impeller o-ring while installingthe impeller (SB Blenders only).Slide impeller onto the shaft and overthe key. Push impeller against theseal driver or shim (SB Blenders).See Figure 15.

8. Install the impeller nut and impel-ler nut gasket, Figure 16 .

9. Once again insert a 3/8” bar intothe hole of the stub shaft to hold therotating parts while tightening theimpeller nut. See Figure 17.

10. Check the stub shaft run out. Fixan indicator to the pump. See Figure18. Total indicator run out should notbe greater than 0.003” (0.075mm). Ifstub shaft run out is greater than0.003” remove the shaft guard, loos-en collar, and then snug the shaftcollar (do not torque yet). Mark thehighest point of run out with a greasemarker. Using a dead blow hammertap stub shaft at high run out pointand recheck run out. If run out isunder 0.003” torque shaft collarscrew and reassemble pump. If notrepeat this step until run out is under0.003”.



11. Replace cover gasket, cover, wing nuts, and shaft guard. When replacing the cover, de-pending on the style of connection, the cover may only be installed correctly with one orienta-tion. Note the orientation of flange bolt hole patterns before installing the cover. Make surethe wing nuts are tight and turn the impeller slowly with a 15/16” socket, extension, and ratchetto check if impeller turns freely .

Note: Always turn the stub shaft by hand before start up making sure nothing is rubbing inside the motor, such as foreign objects or the impeller touching either the back inside of the casing or the cover. Also never run this pump dry. Silicon carbide seals will heat up instantly at oper-ating RPMs and will no longer seal when damaged.

WARNING: Mechanical seal must never run dry. Seal damage will result.

Assembly Ampco Pumps Company


Setting The Impeller Clearance

Assemble the pump as described in the Pump Assembly and Seal Installation section of this manual. For double seals perform steps 1-10 and for single seals perform steps 4-10 of the Pump Assembly and Seal Installation instructions. Take note that the shaft collar screw must be torqued to the proper torque value as determined by the frame size of the motor. Using a torque value less than the prescribed value may allow the shaft to move toward the cove and cause damage to the pump.

Tools Required:

∗ 7/16” wrench ∗ Torque wrench

∗ 15/16” socket wrench ∗ 3/8” round bar

∗ Dead blow hammer ∗ Hex socket ( for size see technical data)

∗ 0.04” (1.0mm) Shim for SB &SBH V Pumps

1. Remove the cover wing nuts, cover, covero-ring, shaft guard, impeller nut, impeller nutgasket, and impeller as described in thepump disassembly part of this manual. ForSB models make sure the thinnest impellershim is on the stub shaft .

2. Loosen the socket head cap screw in theshaft collar and retighten it just enough so thestub shaft is still able move on the motorsshaft. Figure 19.

3. Once the stub shaft is able to slide on themotor shaft place the plastic stub-shaft setting shim on the back of the impeller, over theimpeller hub. Figure 20.

Figure 19

Figure 20



4. With the seal driver, the thinnest shim(SB models), and key on the stub shaft,slide the clearance shim and impeller on tothe stub shaft and tighten the impeller nuton the stub shaft, Figure 21. While push-ing the impeller nut, impeller, and shaft col-lar towards the motor slightly pinching theimpeller clearance shim, tighten the sockethead cap screw in the shaft collar. Torquethe socket cap screw to the right torquevalue that correlates to the frame size ofthe motor. When the shaft collar screw isnot torqued to the correct value the shaftmay move during pump operation althoughthe shaft cannot be moved by hand alongthe motors axis. Torqueing the shaft collar screw more than the recommended val-ue may break the screw.

5. Now that the impeller clearance is setthe clearance shim has to be removed andpump reassembled. Insert a 3/8” bar intothe hole of the stub shaft and loosen theimpeller nut. See Figure 22.

6. Remove the impeller nut, impeller, stub-shaft, setting shim, and clearance shim,Figure 23.

8. Install the impeller o-ring into the back ofthe impeller (SB models only) Figure 25.

9. Install the impeller nut gasket and impel-ler nut. See Figure 26.

10. Replace cover gasket, cover, wing nuts,and shaft guard, Figure 27. When replac-ing the cover, depending on the style ofconnection, the cover may only be installedcorrectly with one orientation. Note the ori-entation of flange bolt hole patterns beforeinstalling the cover. Make sure the wingnuts are tight and turn the impeller slowlywith a 15/16” socket, extension, and ratchetto check if impeller turns freely. If the impel-ler does not turn freely do not force it toturn and absolutely do not run the pump.Reset the impeller clearance.Figure 27

Piping Configuration

Suction and discharge piping must be properly supported and aligned with the pumps suction and discharge ports.

Avoid throttling valves in the suction line of the system.

Check valves must be at a minimum of 5 feet (1.5m) from the pump’s discharge, Fig-ure 28.

Keep the suction piping short and direct as possible. Avoid elbows in the suction line of the system. If this is unavoidable, locate the elbow as least 5 pipe diameters away from the pumps inlet and elbows should not have a radii less than twice the diame-ter of pipe, Figure 28.

Make sure that the NPSH available is always greater than the system’s NPSH re-quired.

Avoid bending piping over piping as this will cause the formation of an air pocket in the suction line. Figure 29.

Route piping under any obstructions when- ever possible. Figure 30.

When using a reducer on the suction end the reduced centerline should not be below the suction centerline as in Figure 31. The centerline of the small diameter end of the reducer should be above the centerline of the suction line as in Figure 32. Injection line angles should be 45º or less. Figure 33 .

delinquent balances at the rate of 1 ½% per month.

4. DELIVERY. Except as otherwise provided expressly stated in the agreement, Products are sold F.O.B. Milwaukee. Seller will use

reasonable commercial efforts to fill orders within the time stated, but the stated delivery date is approximate only, and Seller reserves the right

to readjust shipment schedules without liability. Acceptance by Purchaser of the Products waives any claim for loss or damage resulting from a

delay, regardless of the cause of the delay. Except as otherwise provided herein, Seller will not be responsible for freight, transportation,

insurance, shipping, storage, handling, demurrage or similar charges. Claims by Purchaser for shortages in the Products must be made to Seller

in writing within ten (10) days after date of receipt of the Products. No such shortage shall entitle Purchaser to withhold payment for Products

which were received by Purchaser. Each such claim shall set forth in detail the basis and amount of such claim.

5. TAXES AND FEES. Seller shall pay all present and future sales, excise, privilege, use or other taxes, customs duties, and all other fees or

other costs, imposed by any federal, state, foreign, or local authorities arising from the sale, purchase, transportation, delivery, storage, use or

consumption of the Products or will, if applicable, provide Seller with an appropriate exemption certificate. Seller shall be under no obligation

to contest the validity of any such taxes or to prosecute any claims for refunds or returns.

6. INSTALLATION. The Products shall be installed by and at the expense of Purchaser.

7. LOSS, DAMAGE OR DELAY. Seller will not be liable for loss, damage or delay resulting from causes beyond its reasonable control,

including, without limitation, strikes or labor difficulties, lockouts, acts or omissions of any governmental authority or Seller, insurrection or

riot, war, fires, floods, Acts of God, breakdown of essential machinery, accidents, embargoes, cargo or material shortages, delays in

transportation, lack of production capacity or inability to obtain labor, materials or parts from usual sources. In the event of any such delay,

performance will be postponed by such length of time as may be reasonably necessary to compensate for the delay. In the event performance

by Seller under the agreement cannot be accomplished by Seller due to any of the foregoing causes within a reasonable period of time, Seller

may, at its option, terminate the agreement without liability.

8. RETURNS. No Products or parts may be returned by Purchaser without the prior written consent of Seller.

9. WARRANTY. Seller warrants that the Products manufactured by Seller will be free from defects, material and workmanship under normal

use and service for a period of one (1) year from date of shipment. In addition, the specified rating of each pump is warranted; however, the

characteristic shape of the performance curves may vary from the published standards, and the capacity, head and efficiency guarantees are

based on actual shop tests using clear cold water, and therefore the rating is specified in equivalent units of clear cold water. The sole

obligation of Seller and the exclusive remedy of Purchaser for breach of this warranty shall be the repair (at Seller’s facility) or replacement by

Seller (F.O.B. Milwaukee, Wisconsin), at Seller’s option, of any parts found to be defective, without charge and shall be conditioned upon

Seller receiving written notice of any alleged breach of this warranty within a reasonable time after discovery of the defects, but in no event

later than the end of the warranty period. The parts alleged to be defective shall be returned to Seller upon its request, freight prepaid. This

warranty does not cover ordinary wear and tear, abuse, misuse, overloading, alteration or Products or parts which have not been installed,

operated or maintained in accordance with Seller’s written instructions. Seller shall not be liable for any expenses for repairs, additions or

modifications to the Products outside of Seller’s factory without its prior written consent, and any such repairs without such consent shall void

this warranty. THIS WARRANTY IS EXCLUSIVE AND IS IN LIEU OF ALL OTHER EXPRESS AND IMPLIED WARRANTIES

WHATSOEVER, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A

PARTICULAR PURPOSE. Seller may from time to time provide its facilities, personnel and experience to assist customers in the selection of

materials, design, installation and operation of Products for maximum resistance to corrosion and abrasion with due consideration to the

economy of the installation. This service is provided in an advisory capacity only and the final selection and operation of the Products and

ancillary equipment shall be the sole responsibility of Purchaser or any user thereof. Accessories and parts manufactured by third parties are

warranted only to the extent of such third party’s warranty. IN NO EVENT SHALL SELLER BE LIABLE UNDER ANY

CIRCUMSTANCES FOR ANY INCIDENTAL, CONSEQUENTIAL OR SPECIAL DAMAGES (INCLUDING, WITHOUT LIMITATION,

ANY LOST PROFITS OR LABOR COSTS) ARISING FROM THE BREACH OF THIS WARRANTY OR OTHERWISE ARISING FROM

OR RELATING TO THE PRODUCTS OR THEIR SALE, USE OR INSTALLATION.



10. CHANGES. Changes in any work to be performed hereunder may be made only upon Purchaser’s written instructions and acceptance by

Seller in its discretion. Any change in drawings, materials or design of the Products, or to tools, fixtures or other items used to produce the

Products, which affects Seller’s cost to produce the Products will entitle Seller to adjust the price to take into account any additional costs. If

work has been started, Seller shall be properly reimbursed for work already performed; if Products already produced are not accepted by Purchaser, Seller has the right to adjust the price to take into account any additional costs caused by an increase or decrease in quantities or in

the time required for performance under the agreement.

11. TERMINATION. After Seller has commenced work, ordered any materials or made any other commitments pursuant to the agreement, it

may be terminated only with the prior written agreement of Seller providing for equitable cancellation charges. Such charges shall reimburse

Seller for any completed items at the contract price, and for any work-in-process items at the contract price less the cost to complete.

Termination on any other basis must be specifically agreed on in writing in advance between Purchaser and Seller.

12. DEFERRED DELIVERIES. Orders or deliveries will be deferred only upon the prior written agreement of Seller in its discretion, and

then only upon the following conditions:

(a) The deferral period may not exceed sixty (60) days. At the end of the deferral period, if no release is provided by Purchaser,

Seller reserves the right to render an invoice for and ship the completed portion of the order to the destination specified in Purchaser’s order, or

to store such material at Purchaser’s expense at Seller’s standard storage charges then in effect.

(b) For the portion of the order that is not completed, if no release is provided by Purchaser at the expiration of the deferral period,

Seller reserves the right to render an invoice for any completed items at the contract price, and for any work-in-process items at the contract

price less the cost to complete.

(c) Purchaser shall bear the risk of loss or damage to materials held at Purchaser’s request.

13. LIMITATION OF LIABILITY. IN NO EVENT SHALL SELLER BE LIABLE UNDER ANY CIRCUMSTANCES: (a) FOR ANY

INCIDENTAL, CONSEQUENTIAL OR SPECIAL DAMAGES (INCLUDING, WITHOUT LIMITATION, ANY LOST PROFITS OR

LABOR COSTS) ARISING FROM OR RELATING TO THE PRODUCTS OR THEIR SALE, USE OR INSTALLATION; (b) FORDAMAGES TO PROPERTY (OTHER THAN THE PRODUCTS PURCHASED FROM SELLER); (c) FROM ANY BREACH OF ITS

WARRANTY OR ANY OTHER OBLIGATIONS TO BUYER; OR (d) FOR ANY OTHER CAUSE WHATSOEVER, WHETHER BASED

ON WARRANTY (EXPRESSED OR IMPLIED) OR OTHERWISE BASED ON CONTRACT, OR ON TORT OR OTHER THEORY OF

LIABILITY, AND REGARDLESS OF ANY ADVICE OR REPRESENTATIONS (WHETHER OR NOT IN WRITING) THAT MAY HAVE

BEEN RENDERED BY SELLER CONCERNING THE DESIGN, MANUFACTURE, SALE, USE OR INSTALLATION OF THE

PRODUCTS.

14. INFRINGEMENT. Seller at its expense will defend and hold Purchaser harmless from and against all damages, costs and expenses arising

from any valid claim of infringement by a third party with respect to any patent or other intellectual property rights (collectively, the

“Intellectual Property Rights”) caused by Products originally manufactured by Seller, provided Purchaser (a) has not modified such Products,

(b) gives Seller immediate notice in writing of any claim or commencement or threat of suit, and (c) permits Seller to defend or settle the same,

and gives all immediate information, assistance and authority to enable Seller to do so. In the event any such originally manufactured Products

are held to infringe an Intellectual Property Right and if Purchaser’s use thereof is enjoined, Seller will, at its expense and option: (1) obtain for

Purchaser the right to continue using the Products, (2) supply non-infringing Products, (3) modify the Products so that they become non-

infringing, or (4) refund the then market value of such Products. In no event shall Seller’s liability exceed the sale price of the infringing

Products. THE FOREGOING REPRESENTS SELLER’S ENTIRE AND EXCLUSIVE OBLIGATION WITH RESPECT TO ANY CHARGE

OF INFRINGEMENT OF ANY INTELLECTUAL PROPERTY RIGHT AND IS IN LIEU OF ANY STATUTORY WARRANTY

RELATING TO INFRINGEMENT. Notwithstanding the foregoing, Seller shall have no liability as to any Products or parts thereof that are

manufactured or modified by Purchaser or a third party, or that are manufactured or modified by Seller in accordance with Purchaser’s

specifications. Purchaser will defend and hold Seller harmless from and against all damages, costs and expenses whatsoever arising from any

claim for infringement of any Intellectual Property Rights relating to Products that have been manufactured or modified by Seller according to

specifications provided by Purchaser.

15. CERTAIN LAWS. Seller will comply with the applicable requirements of the Fair Labor Standards Act of 1938, as amended, Executive

Order 11246, and THE rules, regulations and orders of the Secretary of Labor relating thereto.

16. PERIOD FOR ACCEPTING QUOTATIONS. Unless accepted without modification within thirty (30) days of issuance, or prior to

withdrawal by Seller if earlier, all quotations automatically expire at the end of such thirty (30) day period.



17. PROVISIONS FOR INTERNATIONAL TRANSACTIONS. The following provisions shall apply if the Products are to be shipped to

Purchaser at a location outside the United States, and apply regardless of other provisions set forth in these Terms and Conditions:

(a) The 1980 United Nations Convention on Contracts for the International Sale of Products shall not apply.

(b) Except as otherwise provided expressly stated in the agreement, terms of delivery are Ex-Works (within the meaning of

INCOTERMS 2000) and all customs fees, import duties, cargo insurance, taxes and other charges imposed on or relating to the purchase or sale

of the Products shall be paid by Purchaser in addition to the stated price.

(c) Except as otherwise provided expressly stated elsewhere in the agreement, payment shall be made by issuance to Seller of an

irrevocable letter of credit which (i) is issued and confirmed by a U.S. bank acceptable to Seller, (ii) is governed by the Uniform Customs and

Practice for Documentary Credits (UCP 600) and otherwise acceptable in form and substance to Seller, and (iii) provides for payment to Seller

of the purchase price in U.S. dollars upon presentation by Seller of Seller’s certification and/or such other documents as shall be required by the

letter of credit. All banking and other charges for such letter of credit shall be for the account of Purchaser.

(d) Prices include Seller’s standard commercial export packaging which may vary depending on whether shipment is made by air,

land or sea. Except as otherwise provided expressly stated in the agreement, Purchaser will bear any additional expenses required to satisfy

Purchaser’s packaging requirements. Packages will be marked in accordance with Purchaser’s instructions, if any. Seller shall furnish packing

lists and such other information as may be necessary to enable Purchaser’s agent to prepare documents required for export shipment.

(e) All shipments hereunder are subject to compliance with the U.S. Export Administration Act, as amended, regulations thereunder

and all other U.S. laws and regulations concerning exports. Purchaser shall comply with all such laws and regulations concerning the use,

disposition, re-export and sale of the Products provided hereunder.

18. GENERAL. No modification or waiver of the agreement or any of its provisions is valid unless expressly agreed to by Seller in writing,

and no waiver by Seller of any default under the agreement is a waiver of any other or subsequent default. The unenforceability or invalidity of

one or more of the provisions of the agreement will not affect the enforceability or validity of any other provision of the agreement. Purchaser

may not assign any of its rights, duties or obligations under the agreement without Seller’s prior written consent and any attempted assignment

without such consent, even if by operation of law, will be void. The agreement is governed by and shall be construed in accordance with the

laws of the State of Wisconsin, including the Uniform Commercial Code as enacted by such state, without giving effect to its conflict of laws

principles.
